TECHNICAL FIELD [0001] The present invention relates to a training apparatus to be used when muscles of shoulder parts, arm parts and a rear part are trained. BACKGROUND ART [0002] Training apparatuses which are used for training muscles of shoulder parts and a rear part include pull-down training apparatuses. With such a training apparatus, a user who sits on a seat grips one grip bar with both hands stretched upward, and pulls down the grip bar to pull up weights connected to the grip bar. As a result, a load is applied to the muscles of the shoulder parts and the rear part, so that the muscles are trained. [0003] Training apparatuses which are used for training muscles of shoulder parts and arm parts and a rear part are trained include dipping machines. With such a training apparatus, a user who sits on a seat pulls up shoulders and bends elbows to grip the grip bars positioned in a vicinity of both sides of the user's body with both hands, respectively, and pushes down the grip bars to pull up weights connected to the grip bars. As a result, a load is applied to the muscles of the shoulder parts, the arm parts and the rear part so that the muscles are trained. [0004] In the above training, a load of the weight of the weights is applied to the movement for pushing down the grip bars till the last. Such training is called ending movement load training, and the load is applied till the last and strong muscle strength is displayed at each joint angle, thereby strengthening the muscles with the strong tension (hardening) of the muscles (see Patent Document 1 and Non-patent Document 1). [0005] Patent Document 1: Japanese Patent Application Laid-Open No. 2004-187724 [0006] Non-Patent Document 1: "New Training Revolution, New Version" written by Yasushi Koyama, Kodansha Ltd., Sep. 12, 1994, pp. 8 to 13 DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention [0007] However, since muscles obtained by the ending movement load training are less soft and less elastic, there is a problem that body movements necessary for actual competitive sports are lost. Further, since the muscle strength is output from parts where less muscle strength may be output and training is made in an moving form and an output form different from the actual moving forms in the ending movement load training, there is a problem that users feel discomfort in the body movements. Since the supply of oxygen to muscular cells is disturbed by the tension of muscles and blood stream cannot be washed out, there is a problem that fatigue substance such as produced lactic acid are stored, and burdens such as muscle ache and fatigue on bodies become large. The hardening of the muscles is the big cause of injury. [0008] The present invention is devised in view of the above problems, and its object is to provide a training apparatus which is capable of obtaining soft and elastic muscles of shoulder parts, arm parts and a rear part with the hardening of the muscles being caused and loads such as muscle pain and fatigue on a body being less. Means for Solving Problems [0009] In order to achieve the above object, a training apparatus according to a first aspect includes: a seat part; a load application part the magnitude of a load can be adjusted; right and left guide poles extending vertically with a predetermined interval so that the seat part is in their center position; two lifting parts guided by the right and left guide poles to be movable up and down, respectively; rotating parts connected to shafts fixed to the two lifting parts, respectively, to be rotatably provided to the lifting parts; pulling members whose one-side ends are connected to the load application part and whose other ends are connected to the lifting parts; and load transmission parts connected to the other ends of the pulling members in the lifting parts to apply the loads to rotations of the rotating parts about the shafts by means of the load application part. [0010] The training apparatus of a second aspect according to the first aspect is characterized in that the two lifting parts are guided by fitting the right and left guide poles in to one-side ends of the two lifting parts to be movable up and down and rotatable horizontally, the shifts are fixed to the other ends of the two lifting parts, respectively, and the rotating parts connected to the shafts are rotatably provided below the lifting parts, and the other ends of the pulling members are connected to parts of the lifting parts closer to the other ends than the fitting positions of the guide poles. [0011] The training apparatus of a third aspect according to the first aspect is characterized in that the two lifting parts are guided by the right and left guide poles to be movable only up and down, respectively, and the rotating parts connected to the shafts are rotatably provided above the lifting parts. [0012] The training apparatus of a fourth aspect according to any one of the first to third aspects is characterized in that the seat part, the load application part and the right and left guide poles are fixed to predetermined positions in one frame. [0013] The training apparatus of a fifth aspect according to the fourth aspect is characterized in that the load application part is composed of weights supported to the frame movable up and down and connectable/detachable to/from one another. [0014] The training apparatus of a sixth aspect according to any one of the first to fifth aspects is characterized in that the load transmission part includes: a rotation transmission part which transmits a rotation movement about the shaft of the rotating part; and a crank mechanism part which converts the rotational movement transmitted by the rotation transmission part into an up and down movement of a sliding shaft connected to the other end of the pulling member. [0015] A training apparatus of a seventh aspect is characterized in that a load transmission part includes: a rotation transmission part which transmits a rotation movement about a shaft; and a crank mechanism part which converts the rotational movement transmitted by the rotation transmission part into an up and down movement of a sliding shaft connected to the other end of a pulling member whose one end is connected to the load. EFFECTS OF THE INVENTION [0016] According to the training apparatus from the first aspect, when a user sat on the seat part is retaining the rotating parts in the suitable vertical position with both hands and simultaneously rotates them, muscles of user's predetermined portions are "relaxed", and the rotating parts are biased up by the loads of the load application part via the pulling members. For this reason, the muscles of the user's predetermined portions are "stretched". While rotating the rotating parts to a direction opposite to the former rotating direction and further making the "relaxing" and "stretching" movement so that the suitably "stretched" muscles are reflected, the user "contracts" the muscles of the predetermined portions against the loads of the load application part. When the rotating parts are rotated to the direction opposite to the rotating direction with respect to the lifting parts, this movement is partially against the loads of the load application part, so that the loads in the first movement for moving the rotating parts and the lifting parts up and down are reduced. When the forces of the hands are released, the moved lifting parts are guided by the guide poles to be return to its original position by the function of the load application part, and thus the same movement is repeated. A series of the "relaxing-stretching-contracting" movements are promoted, and co-contraction is prevented. As a result, the functions of nerves and muscles and cooperativeness are heightened, and thus the soft and elastic muscles can be obtained with the burden on the body such as muscle pain and fatigue being reduced and the hardening of the muscles not being caused. Further, when aerobic metabolism is stimulated with less forcible rise in a heart rate and blood pressure, this training is effective for the protection against lifestyle-related diseases such as diabetes and high pressure and the cure promotion of ligament damage, fracture and the like, and states, which are useful for bodies, such as elimination of stresses on nerves, muscles and joints and elimination of waste products can be created. [0017] According to the training apparatus from the second aspect, when the user sat on the seat holds the rotating parts with stretched-up hands and twist the upper arms outward, the user's shoulders and arms are "relaxed", and the grip parts are biased up by the loads of the load application part via the pulling members. For this reason, the muscles of muscles near shoulder girdle are suitably "stretched". While further making the "relaxing" and "stretching" movement to twist the upper arms outward so that the suitably stretched muscles near the shoulder girdle are "reflected", the user bends both arms against the loads of the load application part and "contracts" the muscles so as to pull the grip rotating parts down. When the user twists the upper arms outward to rotate the rotating parts, this movement is against part of the loads of the load application part so that the load on the first movement for pulling down both arms is reduced. When both the arms are bent to pull the grip rotating parts down, the "relaxing" and "stretching" movements are being made by further twisting the upper arms outward so that the suitable "contracting" timing is allowed to appear. Therefore, the respective muscle groups obtain the "relaxing-stretching-contracting" timing, so that the movements can be made in good cooperation. Since the other ends of the pulling members are connected to the parts of the lifting parts closer to the other ends than the fitting position of the guide poles, the lifting parts are rotationally biased by the loads of the load application part via the pulling members. The user widens both the arms so that the lifting parts gradually face outward against the rotational biasing force and simultaneously bends both the arms to pull the grip parts down. At this time, the rotational biasing force to be the resistant force with respect to the outward widening of both arms is reduced according to the pulling-down of the grip parts by means of the bending of both the arms. For this reason, when the user bends both the arms to pull the rotating parts down, the user outputs approximately constant muscle strength to widen both arms outward, so as to pull the rotating parts down and simultaneously be capable of smoothly and gradually widening both arms outward. Therefore, the co-contraction of the muscles can be prevented. Since the pushed-down lifting parts are guided by the guide poles according to the function of the load application part when the forces of the hands are released, the same movements as the aforementioned ones are repeated. As a result, a series of the "relaxing-stretching-contracting" movements are promoted, and co-contraction is prevented, thereby heightening the functions of nerves and muscles and cooperativeness and thus obtaining the soft and elastic muscles with the burden on the body such as muscle pain and fatigue being reduced and the hardening of the muscles not being caused. [0018] According to the training apparatus of the third aspect, when the user sat on the seat part grips and pushes the rotating parts with the hands pushed up near the shoulder parts and simultaneously twists the wrist, since the shoulder parts, arm parts and rear part are "relaxed" and the hand-pushing rotating parts are biased to the up direction by the loads of the load application part, the muscles of the rear part such as latissimus dorsi are suitably "stretched". The user is making the "relaxing" and "stretching" movements in order to further twist the upper arms outward so that the suitably "stretched" muscles of the rear part are "reflected", and simultaneously stretches both arms against the loads of the load application part and "contracts" the muscles of the rear part to pull the grip rotating parts down. When the user twists the wrist inward to rotate the rotating parts, this movement is against some of the loads of the load applications parts, and the loads at the first movement for stretching both the arms are reduced. Since the pushed-down lifting parts are guided by the function of the load application part and simultaneously ascend when the forces of the hands are released, the same movements as the above ones are repeated. When both the arms are stretched to push the grip rotating parts down and the muscles of the rear part are contracted, the "relaxing" and "stretching" movements are being made by further twisting the upper arms outward so that the suitable "contracting" timing is allowed to appear. Therefore, the respective muscle groups obtain the "relaxing-stretching-contracting" timing, so that the movements can be made in good cooperation. Further, since the lifting parts are guided by the guide poles so as to be movable up and down, the user can smoothly stretch both the arms to push the rotating parts down, thereby preventing the co-contraction of the muscles. As a result, a series of the "relaxing-stretching-contracting" movements are promoted, and co-contraction is prevented, thereby heightening the functions of nerves and muscles and cooperativeness and thus obtaining the soft and elastic muscles with the burden on the body such as muscle pain and fatigue being reduced and the hardening of the muscles not being caused.
